To assist you further, would you please confirm the product name where you were trying to reset your password?
Hi, I had this same problem and it turned out that it was because I have a password manager program that auto-fills in the password. That was messing up what was going on. What I did to fix it was open a different browser that does not have that auto-fill function set up. then I clicked the "forgot password" thing, filled in my email and it sent me the email. Then when I clicked on the link in that email, the link worked.
